Read the list of individuals to whom this "sophisticated" personality clustering technique was sent. You've got people like A.V. Aho, R.W. Hamming, J.B. Kruskal, J.R. Pierce, K. L. Thompson, J.W. Tukey (and probably more who I didn't recognize). That sort of sheer concentration of talent is a rare and precious thing.
